Answer:
It happens sometimes, explanation of how/why by a vet

There is a condition in female dogs and cats known as "ovarian remnant
syndrome" in which a spayed female continues to exhibit signs of estrus
(heat periods. Usually this occurs because a portion of an ovary was left
in the abdomen during the spay surgery. This can happen several ways --
sometimes the surgeon doesn't have a clear view of the ovary for some
reason (obesity, not having a big enough incision, bleeding, etc.) and a
portion is simply missed, other times it is a piece of the ovary is
accidentally dropped as it is removed and reimplants in the abdomen. I have
had a couple of patients in our practice that appeared to have small pieces
of ovary near the normal ovarian tissue but separate from it. So far we
have seen these pieces and removed them but I tend to think that there are
times when there is just extra ovarian tissue. Dogs that have ovarian
tissue that is not removed during a spay tend to show all the normal signs
of heat -- swelling of the vulva, bleeding, attraction of male dogs and
often false pregnancy signs. These usually occur at the same interval as
other estrus periods, roughly seven months ...... Mike Richards, DVM
